NAME
	GetGBuffers -- Attempt to allocate ALL buffers of an entire AnimOb.

   SYNOPSIS
	status = GetGBuffers(anOb, rp, db)
	D0                   A0    A1  D0

	BOOL GetGBuffers(struct AnimOb *, struct RastPort *, BOOL);

   FUNCTION
	For each sequence of each component of the AnimOb, allocate memory for:
	    SaveBuffer
	    BorderLine
	    CollMask and ImageShadow (point to same buffer)
	    if db is set TRUE (user wants double-buffering) allocate:
	        DBufPacket
	        BufBuffer

   INPUTS
	anOb = pointer to the AnimOb structure
	rp   = pointer to the current RastPort
	db   = double-buffer indicator (set TRUE for double-buffering)

   RESULT
	status = TRUE if the memory allocations were all successful, else FALSE

   BUGS
	If any of the memory allocations fail it does not free the partial
	allocations that did succeed.
